What Is the Limit for Prolonged Sleep Reduction? An Objective Evaluation of the Leonardo da Vinci Ultrashort Sleep Strategy

Abstract

Leonardo da Vinci is a symbol of universal, interdisciplinary wisdom. With his tireless sense of curiosity, Leonardo explored more disciplines than any of his contemporaries. These disciplines included, among others, mathematics, mechanics, ballistics, anatomy, medicine, botany, geology, astronomy, and visual arts. Despite his own prolific writings and the multitude of scholarly works that have since been written about him, however, many aspects of his life remain a mystery. The legends circulated about his inventions and discoveries in all disciplines are numerous, as are postulations concerning his work patterns and life-style (Brion, 1959).
